This month I find out that animals should be careful when choosing a mate, picking a partner that matches them in quality, else they might face an early grave! I discover that a mutation in a taste receptor gene has helped macaques in Japan to become thieves. And in the scientific spark, I talk to Kate Umbers from the University of Western Sydney, who works on a variety of topics, mainly related to understanding the mechanisms, functions and evolution of biological colouration. She tells me what sparked her interest in becoming a scientist.  Download the MP3 A Japanese Macaque munching on fruit (image: https://www.flickr.com/photos/gingiber/) Quicklinks: Becky Kilner's Burying Beetle Lab  Burying Beetle paper in eLife  Japanese Macaque taste receptor paper in PLOS One Kate Umbers' lab page
